  • the present invention generally is directed toward methods of controlling bacteria, including spore formers, yeast, and fungal levels in beverage products by injecting a quantity of a peroxy acid into the beverage product.

While pasteurization eliminates most microorganisms present in the juice, it is not 100% efficacious against all microorganisms, particularly against thermophilic microorganisms. Certain spores and thermophilic bacteria can survive the evaporation and pasteurization processes only to grow when the juice concentrate is re-constituted resulting in taste and odor problems in the final product. Further, even if bacterial cells and spore levels are initially low, they tend to increase in number between the time the juice is filtered to the time it is concentrated and/or reconstituted.

Abstract

La présente invention a pour objet des procédés permettant de réduire les bactéries sporulées thermophiles qui peuvent conduire à des odeurs et des goûts atypiques dans des produits de boissons, en particulier des produits de jus de fruits ou de légumes. Les procédés utilisent un ou plusieurs peroxyacides qui sont ajoutés au système de manipulation de boissons avant pasteurisation et concentration du produit de boisson. En particulier, le peroxyacide est ajouté avant la filtration finale du produit de boisson en amont du pasteurisateur et du concentrateur.
